Length, Time and Money: Class 1 Study Guide
We measure things to compare them. Time tells us when things happen and money helps us buy what we need.
Children learn to compare length (long and short, tall and short), weight (heavy and light) and capacity (more and less water). They can use hand spans, footsteps and pencils to measure before using a ruler.
A week has seven days (Monday to Sunday) and a year has twelve months. Indian money uses rupees (₹). Coins are ₹1, ₹2, ₹5 and ₹10, and notes are ₹10, ₹20, ₹50, ₹100 and more.
Comparing
Put objects side by side with their ends lined up. The one that goes further is longer. For weight, hold items in each hand or use a balance, and the heavier side goes down.
| What | Words | Example |
|---|---|---|
| Length | long, longer, short, shorter | A ruler is longer than a pencil. |
| Height | tall, taller | A tree is taller than a gate. |
| Weight | heavy, heavier, light | A pumpkin is heavier than a tomato. |
| Capacity | more, less | A bucket holds more than a mug. |
Days, months and calendar
The days: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday. Each festival falls in a particular month, for example Independence Day on 15 August and Republic Day on 26 January. A calendar helps us find the date and day.
Look for today's date.
Monday, Tuesday…
How many days to Sunday?
Rupees and paise
₹1 has 100 paise, though paise are rarely used today. Children practice adding coins: ₹2 + ₹5 = ₹7. Role-play shopping is a fun way to learn: set up a pretend shop with price tags up to ₹20 and use play money.
| Coins / notes | Value |
|---|---|
| Coin | ₹1, ₹2, ₹5, ₹10 |
| Notes | ₹10, ₹20, ₹50, ₹100 |
| 5 coins of ₹2 | ₹10 |
Worked examples and common mistakes
Example: A pencil costs ₹5 and an eraser costs ₹2. Total: ₹7. Example: If today is Tuesday, tomorrow is Wednesday. Common mistakes: measuring from different starting points, confusing the sizes of coins with their values (a bigger coin is not always worth more) and mixing up the order of days. Practise with real objects.
Check your understanding: model answers
1. Line them up at one end and see which goes further; your hand is usually longer than a short pencil. 2. Sunday. 3. ₹5 + ₹2 = ₹7.
